So ive read a lot about the 19mm but I was wondering if anyone has any first hand expenece with the 23mm ? Also is the front strut brace worth it for these cars?

Thanks guys

If you're on stock suspension, either one would tighten up fine. If you are dropped a lot, then 19mm is already too much for bad roads. I'm debating whether to take mine off and put stock back on.
Read the suspension thread...........
Following Njerald's advice, I got the combo front strut tower brace and 19mm RSB to complement my stock XLE suspension. You can definitely feel the difference and its all good. Don't waste time trying to rationalize the purchase and just buy the parts. You won't regret it.

This is a good idea for stock suspension.

Especially if you have a V6, as you won't be able to put down the power as easily without stiffening the front.

FYI, the OP was not asking about whether to get a RSB, he was asking whether it was worth getting the 23mm vs. the 19mm RSB.

Thank you at least some one here understood what I was asking

I'm definitely going to be buying one just not sure which one gives the best performance. Keep in mind I have a SE V6 and will be getting tein s tech springs.

Btw I've search the suspension thread and a bunch of others but yet have not come up with anything.
I just recently went with the 23mm rear sway bar over the 19mm for my SE V6, I've also got the front strut bar as well as TRD lowering springs.

The 23mm was quite a bit thicker then the stock sway bar, even for the SE V6:



A thicker rear sway bar would induce less understeer, which is more oversteer, usually dangerous for a FWD car, so for those that just simply daily drive it and want a bit better handling, the 19mm is plenty. The 23mm makes the rear quite a bit stiffer, almost like a solid axle over bumps sometimes, but does seem to induce turn in fairly well as it loses a lot of the factory spec'd understeer for the Camry. The car overall feels more flat in turns, but potentially dangerous for high speed corners in wet and bad weather (which you shouldn't be doing anyways)

As for the front strut bar, probably not, more visual then anything that's beneficial, maybe if you've got a fully upgraded suspension on a more track orientated vehicle, the strut bar would help in addition to roll cages and fender braces and stuff, but alone, probably not, more placebo effect then anything honestly speaking, even track-orientated cars such as the GTR doesn't come with a front strut bar from factory, and they handle great without one =)

Thank you for your informations, i always thought that 19mm sway bar is good enought for Camry...and yes, they are FWD.
hmm. many sports cars come with strut tower bars from the factory, my eclipse, previous eclipse, i think the evo's, saab's, and many others. it does work, just not as noticeable as other mods will give you. For example, you can compare track times with and without use and see a difference, after my motor swap i had no strut bar and i could feel the difference. As for sway bars, for front wheel drive cars whose chassis' understeers more than usual i would imagine the 23 mm would be better, BUT after driving the le camry a bit i noticed the understeer is not as bad as it could be (probably because of long wheelbase also helps induce oversteer therefore decreasing understeer) so i would have to concur that the 19mm sway bar should be the best for daily use.

chuck nasty
thanks guys for your input

i think ill be sticking with the 19mm as i live in the northeast and we have alot of snow and rain up here lol. i dont need the wife spinning the car out on me this winter lol.

so here is my next question where is the cheapest place to get the 19mm?

thanks again :)
i have the 23mm on my se v6. it seems solid and way better handling then the stock one. bt it also depends on ur suspension, and tires u know. soo just chose whether u want to pay a lil more for the thicker bar or thinner.
On my 02 Sentra Spec-V that I Daily Drive I have a 25mm rear sway bar and I like it. I also live in the northeast and through last years snow storms I had no problems. b0r1cha is right in my opinion though. the effect that the sway bar will have on your rear end sliding out depends on you suspension setup and your tires. Tires can make a really big difference.

Sorry to hash up old threads, but I found an interesting find over the weekend. My rear sway bar on my 2008 Avalon Touring is the exact same dimensions as the one my friends when he replaced his rear sway bar. I put his old one next to mine and the end links matched up!

Has any installed this rear sway bar on the Avalon? It a much heavier car compared to the +07 Camry so the 23mm rear sway bar should be an excellent upgrade for the Touring edition.
mine is a gen5 SE I4, but the oem RSB was 17mm.. I bought the whiteline 21mm RSB to go with my bc coilovers..

like somone said before, tires are very important too. with cheapo all seasons or whatever, you wont be using the upgraded rsb to its potential. with a set of sticky summer tires, it should really be noticeable.

that said, i cant really tell a difference yet since i put the coilovers on at the same time.. i'll report back after i auto-x it once or twice :naughty:
I have the 23mm rsp, and the front strut tower brace. The strut bar doesn't really do much as far as being able to notice anything. But man oh man does that sway bar kick ass! I LOVE it, and it complements my coils very well.

take that front strut brace off and take an exit ramp, you'll definitely feel a difference... im SO glad my SE came with the oem black one, its very clean and I took it off once just to see the difference. just normal driving you wont feel it, but it tightens up the front pretty good. next up for me is a whiteline front sway

blackcam, what coils did you get? your car is freakin hot :rockon:

ditto, unless you have to money to burn, an aftermarket strut bar or strut brace won't do anything for your handling. Your Camry already has a factory brace integrated between the front struts. might look cool though.
